switching sock with a hole to the other foot, where it will be in a different spot. in 'ancient' times socks would be 'darned', sewn and/or repaired. now that we have a 'disposable' society, one simply throws the offending sock in the "gobbige" can. (or rag bag!)

sock hole shift accomplishes only the delay of this process. of course, if a hole actually comes around, it usually isn't long before the heel goes too...

john had a toe poking through a sock hole, time to sock hole shift; he thought!
